I have a Quiet One 3000 pump that I'm using for a closed-loop on my 40g. It's so incredibly quiet that I have to put my ear within a foot of it just to hear it running.

Thanks for the input. My new tank is a 75gal reef ready with a 30 gal sump. I will have two 150watt 10k metal halide and one actnic 48in vho and one 50/50 48in vho. I currently have a bunch of mag pumps but they all tend to be on the loud side. What size internal pump would someone recommend for this application.
